True.

The Squid default is to cache objects without a explicit expiry time for
20% of their age.

To configure your Squid to have fully strict refresh checks configure it
with

refresh_pattern . 0 0% 0

This forces Squid to validate each request to a object without any
explicit expiry time. Note that this will have a servere impact on your
latency hit ratio.
